Atrazine induction of a family 4 cytochrome P450 gene in <i>Chironomus tentans</i> (Diptera: Chironomidae)
Cytochrome P450-dependent microsomal monooxygenase (P450) activity was measured in control and atrazine-exposed third instar midge larvae, Chironomus tentans. Significantly elevated Odemethylase activity was observed in gut homogenates taken from midges exposed to atrazine concentrations from 1 to 10 ppm for 90 h. No significant induction was observed at atrazine concentrations below 1 ppm. A ...
متن کاملRapid and concerted evolution of repeat units in a balbiani ring gene.
The Balbiani ring (BR) genes in the midge Chironomus, a genus belonging to Diptera, code for large secretory proteins, used to construct the larval tube. The 15-23-kb long core block in each gene consists of an array of tandemly arranged approximately 200-bp long repeat units, where a single repeat unit is composed of a constant and a subrepeat region. In order to investigate the evolutionary f...
متن کاملIsolation, cloning and expression of DNA fragments reflecting open reading frames of 1.8 and 4.6 kb RNAs of the I-18 C gene of Chironomus tentans.
This study, based on the genetic engineering approach, concerns the regulation of the insect gene expression, but it has also a strong significance for plant protection, which is associated with the future possibility to control insect development more effectively, especially in those species that are pests of cultivated plants. The I-18 C gene of Chironomus tentans is activated by heat-shock a...
متن کاملAtrazine induction of a family 4 cytochrome P450 gene in Chironomus tentans (Diptera: Chironomidae).
Cytochrome P450-dependent microsomal monooxygenase (P450) activity was measured in control and atrazine-exposed third instar midge larvae, Chironomus tentans. Significantly elevated O-demethylase activity was observed in gut homogenates taken from midges exposed to atrazine concentrations from 1 to 10 ppm for 90 h. No significant induction was observed at atrazine concentrations below 1 ppm. A ...
متن کاملCloning and expression of an atrazine inducible cytochrome P450, CYP4G33, from Chironomus tentans (Diptera: Chironomidae)
Previous studies performed in our laboratory have measured the effect of atrazine exposure on cytochrome P450-dependent monooxygenase activity and have found increased activity in midge larvae (Chironomus tentans) as a result of atrazine exposure (1– 10 ppm). Here we report the cloning and expression of a specific C. tentans CYP4 gene that is responsive to atrazine induction with an open readin...
